BacSomaticTM provides rapid hygiene testing of milk. BacSomatic is the first-ever integrated bacteria and somatic cell tester and offers full automation for minimal reagent handling and consistent test results.

Integrated bacteria and somatic cell tester

Automatic and fast alternative to manual assay, providing instant, simultaneous results for individual bacteria and somatic cell count within 9.5 minutes and 1.5 minutes for somatic cell count alone.

More accurate than alternative methods

A fully automated procedure avoids the risk of human error and inconsistency, while ready-to-use reagents in an enclosed bag system, ensure the exact same dosage for every measurement. A sensor in the reagent bag indicates the number of available tests remaining. The unique reagent concept includes control samples for quality assurance and GLP. Online remote monitoring ensures consistent performance and high uptime.

Simple and flexible to use

Built on a long heritage of Foss analytical technology and backed by global Foss support, BacSomatic combines robust performance with a modern interface. Very easyto-use with intuitive touch-screen operation for smarter money-saving decisions on how to use milk.

Sample types

Raw cow’s milk and buffalo milk


Individual Bacteria Count (IBC) Somatic Cell Count (SCC)


Flow cytometry technology, counting individual bacteria cells and somatic cells. The IBC results can be converted to CFU results. BacSomatic software includes an easy and rapid tool to develop a robust conversion table between IBC and CFU.

BacSomatic™ - First Ever Integrated Bacteria and Somatic Cell Counter Improves Milk Hygiene Testing

Screening Raw Milk for Hygiene Quality – A New Option for Dairies

Integrated Bacteria and Somatic Cell Counting – How It Works

Foss Analytical

FOSS creates end-to-end solutions that secure and improve food quality. From raw material to finished product. Our analysis instruments refine measurements into information management that enables businesses to run intelligent data-driven productions with less waste and bigger yields. Controlling cost and quality across all sectors and value chains, we help food and agricultural producers limit the number of human errors, scale their business faster and reduce manual labor as well as labor costs. We call it analytics beyond measure.

We cover these food and agricultural industries: Dairy, Feed and Forage, Grain, Flour Milling & Oilseed Processing, Laboratories, Meat, Raw Milk Testing and Wine.

Over the last 60 years, we have made it our business to define the standard of analytical solutions for the food and agricultural industry. We pioneered advanced analysis for the challenging production environments in the 1960’s, and we were the first to integrate chemical composition analysis in process lines. Now our resolve and ambition have also made us the international benchmark in the field of chemometrics and real time analytics.
